PRESSER-FOOT.

Specification of Letters Patent. 1

Application filed January as, 1914. Serial No. 814,553.

To all evil am it may) concern Be it known that I, Lnsmn W. Moses, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvementsin Presser-Feet, of which the following is a specification.

The purposeof this invention is to pro- 1 vide a presser-foot for holding the crowns of straw hats while they are being cut ofi to lower. the crowns. Owing to the fact that crown portions of straw hats of the kind worn by men and boys are oval circumferentially, while the feed wheel upon which they are placedwhile being cut is cylindricahthe rigid curved bars generally used as presser feet for holding the crowns in place against the feed wheels at the cutting points are unsatisfactory, because they do not adapt themselves to the changing contour of the hat crown and tend to catch in the straw and tear'the hats, and also to deflect the crowns from the cutting lines. In carrying out my invention, I provide a pressernfoot which bears upon the crownat two points only, one

in advance and the other atthe rear of the cutting point, so that the hat crowns will always beheld firmly against the feed wheel between these two points. The parts of the presser .foot which engage the crown are in the form of rollers, which ride easily over:

any rough orprojecting portions of the straw, these rollers being spring pressed toward the feed wheel and having a limited vertical movement so as to be self adjusting.

upon the crown.

While the presser foot is designed particularly for use 1n connection with machines for cutting thecrowns of straw hats, or other elevation of a hat trimming machine embodying my improvements; Fig. 2 is an end elevation of the same; Fig. 3 is a side eleva tion of thepresser foot detached; Fig. 4 is a detail; view illustrating a modification in the mounting ;of the presser foot rollers,

adapting them for movement independently;

of one another, and of the connecting bar; and,Fig. 5 isa side elevation of a presser foot illustrating its adaptation to a hat sewin machine.

Iteferring to Figs. 1 to 3, inclusive, of the draw1ng,1 indicates thesupporting frame ofa hat trimming machine, in which is mounted a; feed shaft 2.having thereon a dr1v1ngpulley3, a gear a, and a feed roller 5. The gear 4 meshes with a gear 6 on a cutter shaft 7, which is mounted in a vertically movable frame comprising. arms 8, hinged. to the supporting frame 1, the arrangement being such that when the hinged frame is swung downward until the gears arein mesh,.the two shafts will turn in opposite directions when power is applied to the pulley 3. The feed roller preferably has a milled periphery, as shown, and it is provided with an annular groove 5, into Patented Aug. 4, 1914 whichthe edge of a circular cutter 9, on the chine, is. mounted a lever 10, pivoted centrally at. 10, and to the downwardly turned arm 10 of this lever is secured the shankll 1 of the presser foot a. The presser foot comprisesa metal bar or strip 12, having at each end studs 13whichproject laterally toward the cutter, and upon these studs are mounted rollers 14. The bar 12 is connected pivotally at about its center to the shank 11 by a stud 15, and preferably a slot 16 is formed in the shank concentric with the axis of the stud 15, and a stop-pin l7, on:the bar 12, extends into this slot, the slot and pin connectionpermitting the bar to rock with respect to the shank to a limited extent, to allow the foot to adjust itself to the work, and serving also to. prevent the bar from turning freely about its axis when the presser foot is raised out of engagement with the work. A spring 19 applies tension to the lever to hold the presser foot in engagement with the work on the. feed roller, and an adjusting screw 18, bearing upon the arm 10", is provided for regulating the tension;

In operation, when it is desiredto cut the crown of a hat circumferentially, the

hinged portion of the cutter frame is raised,

lifting the cutter and presser foot away from the feed roller, and the hat, indicated in dotted lines at 20, is I passed over the roller, as shown. The hinged frame is then lowered to bring the cutter and presser foot into engagement with the crown. The rollers 14 on the presser foot are spaced apart and arranged withrespect to the cut- .ter so that. one roller will press upon the crownin advance of the point where the cutter engages it, and the other roller Will,

bear upon the crown at .the rear of the cutting point. I Thus, at the cutting point, the crown will be pressed solidly against the feed roller, and when power is applied to the machine, the cutter and feed roller will revolvein opposite di'rectionsyand the for-v mer will shear off a portion of the hat crown. "As the crowns of, straw hats, and oth'erlstiif hats, as worn by men and boys, have an oval shape circuniiterent ially, it is difficult with the ordinary presser it'oot vto hold the crown; firmly at the cutting point,

because of the constant-lychanging curva- -.ture of the crown. 'Thepresser foot of my invention, however, constantly bears against the crown; at two points only, one in ad- Vance and one at the rear ofthe point where the cutter meets; the groove in the ffeed roller, and by reason of these twopoints of contact and the pivotal mounting of [the bar "12, which carries the 'presser foot roll-x ers, the foot will adjust itself to the chang-' ing contour offthe crown as the latter re: volves, and. will hold the crown firmly against the feed roller at the cutting point midway between the presser foot rollers. The tension of thepresser foot may be ,vari'ed, as will be obvious, by adjusting the screw18.- r Instead of mountingthe bar 12 pivotally and mounting the"rollers upon studs fiXed in said bar, as shown inFig. 3,'which, how-- ever, is the preferred arrangement, the rollers may be arranged as .illustratedin Fig;

4, each roller being mounted in a block 21 adapted to slide in a slot 22,in the bar 12? and normally pressed downwardly by an independent spring 23'. In such caseithe bar 12? maybe secured rigidlyto the shank 11, if desired, and. the vpresserfoot rollers will'have an independent movement -so that they can adjust themselves'totheform of the hat crown. e j

The press'er foot may also be applied to machines for 'sewing-sweatbands into hats, or for-sewing crowns to brims, this being" with the cutting or stitching operations.
